Vapour-Liquid-Solid (VLS) Growth

Vapor-Liquid-Solid (VLS) growth is a process used to create tiny structures called nanowires. It begins with heating a metal catalyst, which forms a liquid droplet. Vapor-phase material then deposits onto this droplet, where it dissolves into the liquid. When the solution becomes saturated, the material starts to solidify, forming a nanowire that grows out from the catalyst. This method allows precise control over the wire's size and direction, making it useful in electronics and nanotechnology applications.
